I am getting the same output on Windows and Linux: the r10k to FFV1 both play incorrectly. In other words, I am not getting different outputs....but the same output. They both play just as bad as the screenshots provided.

No, I've never been able to play R10K. I've not tried R10g either. 

Apparently there are different formats:

R10k (Big Endian) 
R10g (Big Endian)
r10k (Little Endian)
r10g (Little Endian)

Sometimes this gets confusing like v210 (YUV) and r210 (RGB)...which is the mistake I made earlier. 

I am on an Intel machine, so I am living in the Little Endian world....not that it matters as we should be able to create content for either. But, apparently there is a difference. I suppose most content (Blackmagic / AJA) is done via a Mac as they are high end codecs.

For example, I notice that the R10K (http://samples.ffmpeg.org/V-codecs/R10k.mov) is Big Endian whereas the r10k's I've been sharing with you are Little Endian. 

It's just to say, I notice the FFMpeg has no r10k samples! 

Cheers,

Jason
